Characterization of drainage concrete in roads pavements construction

Abstract

The application of concrete in road construction continues to be intense and, in view of the existence of a negative sustainable impact of this material, the development and knowledge of new types that minimize such actions is imperative in the face of new concerns in the context of sustainability. The engineering works have, over time, a significant technological evolution that has provided a better serviceability to the users. As a result of this growth, the characterization and performance of these products and systems, both built and under development, are issues that have preoccupied several sectors of construction civilization, which demands more intense studies about deleterious configurations. This work presents the study of drainage concrete for road pavements, require knowledge of physical and mechanical characteristics of materials. In order to evaluate the behavior of pavements, experimental tests were carried out with several compositions. The rigid pavements with drainage concrete after their construction undergo under the action of traffic and atmospheric conditions. The degradation process occurs over the lifetime of the pavement and may be reduced if it is well constructed and well maintained. In this way it is fundamental to understand which are the tests that must be carried out. In the case of concrete, we have the workability, tests of resistance to compression and bending, permeability tests, compressive strength tests, wear resistance tests, and absorption by immersion tests.
